What I did to handle memos... and it's a HACK... was to create a
function DoMemo that took as arguments the table, the primary key
field of the table, the value of said pk, the field to update, and the
Take the first 200 characters of the string.
Replace all newlines in that substring with "+CHR(13)+" (Or CHR(13)+CHR(10)?)
Then do something like: UPDATE table SET field=First200 WHERE pk=pkvalue
Then take the next 200 characters of the string.
Replace all newlines as above
Do something like: UPDATE table SET field=ALLTRIM(field)+Next200 WHERE
Repeat until you've "consumed" the entire string. This works because
you never put in more that 250 odd characters at a time. It can still
fail though if you have enough newlines to push your 200 characters up
over the 250 odd character limit.
It DOES work if you use RECNO() as the pk field and the appropriate
recno() that you would get if you did something like SELECT recno() AS
myrecno,* FROM sometable (I use the myrecno because otherwise you get
some weird exp_1 field name)
It just popped into my head... I wonder if something like this would work...
UPDATE sometable SET a=1,a=a+1,a=a+1,a=a+1 WHERE x=y
You might be able to limit the total number of calls to the database
that way... If I wasn't in the process of migrating to MySQL I might
give it a whirl... :)
Hope this helps whatever you decide to do.
